As a conclusion we may pressume a symptom trajectory in covid-19 positive tested. Mild sore throat which then progresses to a cough, and shortness of breath?
The bar chart bellow shows symptom across co-morbidity groups. By observing the obesity and hypertensive patients, although we see a similar pattern in symptom manifestation, there are slight differences when it comes to sputum and sore throat. In hypertensive respondents sore throat is more prominent than in obese respondents, which are experiencing more sputum. This is not the same with respondent with asthma, which are experiencing sputum and shortness of breath, where sore throat comes on the fourth place, after muscle ache.
